Klevv GENUINE G560 2TB Gen5.0 SSD Review

We used CrystalDiskMark 8 to test the random performance of the drive at lower queue depths (QD1 – QD8 where most of the everyday workloads occur) using 1 to 4 threads.

Random Reads.

In the QD1-QD8 random read tests the drive produced smooth increases in performance as the queue depth deepened without any noticeable dramas. At QD1 the drive speed ranges from 21,389 IOPS (87.69MB/s) using a single thread up to 84,896 IOPS (347.73MB/s) using four threads. At a QD of 8, the single-thread performance had increased to 157,461 IOPS (644.95MB/s) while the four-threaded test reached 504,630 IOPS (2,066.97MB/s).

Random Writes

In the 4K write tests, the performance rose quickly from QD1 to QD2 for all four tested threads with the increase rising as the the thread count increased. For all the tested threads the performance began to plateau out after QD2 and remained that way until the end of the test at QD8.
